These are sturdy and easy to assemble IF they don't get bent during shipping. I bought 2 of these. The first one took FOREVER to assemble because it was bent "out of square" just a little bit so I had to use a rubber mallet to get the railing in and then it was a nightmare to get the crossbars lined up so the pins would fit in. The 2nd unit went together like a breeze in 15 minutes by myself. I need something to fit in the holes (notated in photo with a red arrow) to be able to hang stuff if anyone has found something. Overall these are AWESOME shelves

I had been looking at purchasing this shelving unit for a couple of months. We finally purchased it a week ago. Very easy to assemble except that a couple of the holes pre-drilled in the shelf slats did not align with the pre-drilled holes in the side rails. One slat we had to take a drill and modify the holes to match. Other than that - no tools are needed.

the shelf itself is perfect. for the price even greater. but what you save in price you lose in QC of Sam's and their shipping partner(s). as MANY have stated you have a high likelihood of some damage to the shelf. my box came in the mail with significant damage. when building it i noticed the top of the main support had been crushed in. i was surprised i was able to assemble it 99% of the way with just one support bolt being impossible to use due to the damage. I was able to get it built minus one support bolt on the top shelf and thankfully Sam's CS online immediately offered me a 25% refund for the damage.

We installed two of these. They are very easy to assemble and are very sturdy.
